Hi, did a search for the answer to my question and found this forum
which seems very knowledgeable about motors and speeds related to them.

I recently had a treadmill motor replaced on my treadmill. The
original motor was 2hp. For some reason the replacement the technician
got was a 2.5hp. After he replaced the motor and left, I noticed that
the speeds of the treadmill now seemed slower than what I set the
treadmill for. After some rough calculations I determined it to be
about 80% of the speed I set. (ie. I set the treadmill to jog at 5
mph, but I am now walking at 4 mph) Does this make sense given that a
larger motor was put in but no changes to the circuit boards etc)
Everything else remained constant.

Really depends on what kind of motor it is and how the speed is controlled.

In any case, I'd get the guy back and have him fix it _right_. He should
have checked it before he left.

Thank you in advance,

Jim
